How important is the Head of School?

Which of the so-called top boarding schools have the best heads of school, and which the worst? Of course, it’s hard to tell with a brand new HOS (like at Andover), and the interim ones are not intended as long-term solutions.

MODERATOR’S NOTE: A valid question. But one that should be asked in a new thread and not hijack this one. Hijacking is considered rude to the original poster.
